Note: I do not have network manager install. To install it, I require wpasupplicant. This means I have to use my mobile phone to download necessary packages, and transfer it via pendrive using OTG.
I have installed Debian 10 buster. Unfortunately no desktop environment installed, no network manager installed.
It's been more than 30 hours and I trying to connect my laptop to the Internet.
Note: I don't have Ethernet port. I use Tp-link TL-WN722N wifi receiver to connect to WiFi. No desktop environment installed.
The ultimate goal is to install wpasupplicant. So that I can install network-manager and use Internet. I have manually installed several deb packages and firmware offline so far.
